This was a retrofit kit for adding the GR system to a Les Paul from the late 80's.
This was cannibalized in order to swap out the good GR pickup with a non functioning pickup and the balance potentiometer in a G505 guitar. Otherwise, the parts are functional.
All original instructions and the (unused) routing/drilling sticker templates are included! Also, the schematic for building your own BC-13 (24-pin to 13 pin converter) are included for fun.
The hex pickup included has a bad coil for one of the segments. (this is the one that went bad in the G505, just in case you'd want to experiment with it.
What you see in the pics is what you get. CC controller buttons, pots, switches, screws, knobs, etc.
A great find for anyone needing parts to repair GR guitars!
